JACOB D. WIN SLOW, OF WILMINGTON,. DELAWARE.

IMPROVED SHUTTER-FASTENING.

Specification forming part of Letters Patent No. 57,239, dated August 14, 1866.

To all whom 'it may concern:

Be it known that I, J. D. WINsLow, of Wilmin gton, Delaware, have invented an Improved Shutter-Fastener; and I do hereby declare the following to be a full, clear, and exact description of lthe same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a shutter-fastener constructed, as fully described hereinafter, so that it may be readily and securely fastened to a wall, and so that the shutter may be held irmly in its place when turned back against the wall.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

0n reference to the accompanying drawings, which form a part of this specification, Figures 1 and 2 are views showing my improved shutter-fastener secured to the wall ot' a building; and Fig. 3, a view looking in the direction of the arrow, Fig. l.

A is a metal plate or bar, one end of which is sharpened, as shown in the drawings, and to a pin, a, projecting from the side of this plate near the blunt end of the same, is hung a lever, B.

The lever B has two arms, Z) b', the outer arm, b, being weighted, and in the upper edge of the inner arm, b', are two slots, o c.

The bar A is rmly secuied to a wall, C, by driving the sharpened end of the same into the space between two bricks of the wall, as shown in Figs. 1 and 2.

In the wall C is secured a window-frame, to one side, D, of which is hung a shutter, E, and at thelower edge of the latter is a projection, c, the said projection being secured in such a position that it will be brought in contact with the edge of the lever B when the shutter is turned back against the wall.

When the projection e is brought in contact with the lever B the inner end of the latter will be depressed, and will be maintained by the weight of the arm b in contact with the projection, so that as the latter is brought over the opening c the lever will rise to the position shown in Fig. 2, the projection being thus confined in the opening c', so that the shutter is held firmly in its place, Should it be desired, however, t0 maintain the shutter in close contact with the wall it is pushed back so quickly that the lever is thrown down from contact with the projection c, the latter passing over the opening c', so that when the 1ever again rises the projection will occupy a position in lthe opening c, as shown in Fig. 1, the shutter being thus held firmly in its position against the wall.

Shutter-fasteners have heretofore been constructed having levers hung to pins projecting from the ends of plates or bars. These are objectionable, however, as, in order to drive the plates firmly into the wall, the pin is frequently so battered that the lever is either riveted to the plate or is secured so firmly to the latter that it is no longer self-adjusting. In such devices, also, the space betweeuthe wall and the lever is so much greater than the width of the shutter that the latter can vibrate between the two, causing a disagreeable rattling noise.

1t will be seen that in the device above described the blunt end of the plate A may be struck as often as necessary to drive the plate firmly in its position without in the least impairing the efficiency of the fastener, and that when the shutter is once secured in its position it cannot vibrate in the slightest degree.

It' necessary, a slotted plate may be secured to the lower edge of the shutter. corresponding projections being made on the lever, the result in this instance being precisely the same as when the slots are in the lever, as above described.

I claim as my invention and desire to secure by Letters Patent- The notched lever B, hung upon the bar A, in combination withV the staple or equivalent device projecting downward from the lower edge of the shutter E, all being arranged and operatin g as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

J. D. WINSLOW.
